macOS in VM not using full size of HDD

[Mike Boreham]

My macOS VM is 256GB in Configuration > Disk Capacity, but in the VM Macintosh HD is only 119GB and I am getting warnings about low space.
How do I make the VM use all the 256GB ?
Thanks

Never mind. Found the answer in https://kb.parallels.com/128867, and in the article linked from that, https://kb.parallels.com/en/125561, which gives detailed Terminal instructions for creating a custom size. These worked perfectly, so I am back in business.
